gdi v1.5.4 (Release date: 2023-09-06)

Changes: * added new tests and vignette

gdi v1.5.3 (Release date: 2023-08-25)

Changes: * added collumn with x axis centroids to output of gdi(), for use in rotI() and hCOM() functions

gdi v1.5.2 (Release date: 2023-08-24)

Changes: * generalized rotI() function to calculate rotational inertia of shapes around any axis * added function to cscorr to allow calculation of correction factors for moment of inertia. * fixed issue in input to functions (rejection of previously read images supplied as matrix or array)

gdi v1.5.1 (Release date: 2023-08-23)

Changes: * added rotI() function to calculate rotational inertia of shapes

gdi v1.5.0 (Release date: 2023-08-19)

Changes: * added csI() function to calculate second moment of area for cross-sectional shapes

gdi v1.4.2 (Release date: 2023-08-08)

Changes: * fixed bug in cscorr (returning inverse aspect ratios depending on settings) – now aspect ratio is always max horizontal diameter/max vertical diameter

gdi v1.4.1 (Release date: 2023-07-28)

Changes: * modifications to image-processing functions to deal with single-channel images

gdi v1.4.0 (Release date: 2023-07-28)

Changes: * added functions vCOM and hCOM and expanded functionality of measuresil() and gdi() to allow estimating the position of the center of mass (COM) * added function plot_sil() to plot silhouettes

gdi v1.3.1 (Release date: 2023-07-22)

Changes: * added parameter setting indices for gdi(), allowing to specify optional indices to specify a subset of the measurement vectors

gdi v1.3.0 (Release date: 2023-06-12)

Changes: * added parameter setting alignment for measuresil(), allowing the optional use of vertically aligned silhouettes if align!=“h” * updated unit tests to check that scale works correctly

gdi v1.2.3 (Release date: 2023-06-12)

Changes: * fixed cscorr() area output scaling (previous version didn’t set the scale for area resulting in unscaled area output even when scale is set)

gdi v1.2.2 (Release date: 2023-06-07)

Changes: * added function sellipse.coo() to visualize shapes of superelliptical cross-sections

gdi v1.2.1 (Release date: 2023-05-05)

Changes: * added tests using package ‘testthat’ * gdi() now also reports the horizontal length of the silhouette as name of output (in the same unit cubed to calculate volume, i.e. decimeters if volume is intended in liters), intended to quickly spot scaling errors

gdi v1.2.0 (Release date: 2023-05-04)

Changes: * added functions imghist() and fdetect() for aiding with setting appropriate threshold and method parameters for measuresil() and cscorr()

gdi v1.1.2 (Release date: 2023-05-04)

Changes: * Fixed missing “,” in description. * Fixed errors in and improved vignette. * Fixed error in cscorr()-function. Previous version would output the diameters of the silhouette in pixels, even if a scale was provided. New version converts them to units determined by scale parameter.

gdi v1.1.1 (Release date: 2023-05-04)

Changes: * Fixed invalid doi in the description.

gdi v1.1.0 (Release date: 2023-05-03)

Changes: * Updated the description, vignettes and documentation.

gdi v1.0.0 (Release date: 2023-04-30)

Changes:
